United Nations. The Blockade of Wonsan , or the Siege of Wonsan , from February 16, to July 27, , during the Korean War , was the longest naval blockade in modern history, lasting days. UN naval forces, primarily from the United States , successfully kept the strategically important city of Wonsan from being used by the North Korean Navy. The blockade diverted communist troops from the front line. North Korean artillery fired at the American fleet was mostly ineffective, and the city was heavily damaged by UN naval aircraft and warships.
Wonsan was a strategic point during the war, located on North Korea's southeastern coast with a large harbor, an airfield, a petroleum refinery , 75, people, and as many as 80, troops, including several artillery batteries. After the Battle of Inchon , in which General Douglas MacArthur landed on the northwestern shores of the Korean peninsula , he ordered X Corps to make a landing at Wonsan where they would proceed west, link up with the Eighth Army and then advance towards Pyongyang , the capital of North Korea.

North Korean naval forces had been well supplied by the Soviet Union and China with all sorts of sea mines and they were used as much as possible to defend Wonsan.
Soviet military advisors were also employed to create more effective mine fields. One of the first objectives of the operation was to begin plotting the locations of mines and then destroy them. Because of this, the use of minesweepers became a necessity and eventually dozens would serve in the blockade.
Operation Wonsan , or the Clearance of Wonsan, began on October 10 of , ten days before the landing was scheduled to take place. Rear Admiral James H.
